Page 16: Chapter 3- Understanding Raid
Chapter 3 - Understanding RAID The SANCube800™ controller subsystem is a high-performance IDE drive bus disk array Controller. When properly configured, the RAID subsystem can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. The RAID subsystem controller connects to the host systems through an IEEE1394B FireWire 800 interface. - Page 17 Pros: Fastest read/write performance of any of the Hybrid RAID levels High data reliability as all the data is redundant Cons: Requires double the raw data storage capacity SANCube800™ Owner’s Manual 3-Understanding RAID...

Page 18: Raid 3
RAID 3 RAID 3 provides disk striping and complete data fault tolerance though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity on the blocks, and then writes the blocks to all but one drive in the array. The parity data created is then written to the last drive in the array. -

RAID level refers to the level of data performance and protection of a Volume Set. - Page 31 Write-Through cache performs all write operations in parallel-- data is written to the storage and the cache memory simultaneously. Write-back caching yields somewhat better performance than write-through caching because it reduces the number of write operations to disk, but is also more prone to data loss due to service interruptions.

IDE disk interface was standardized by ANSI to form the ATA specification using a 16-bit ISA bus. Cache cache is a fast-access memory bank that serves as an intermediate storage for data that is read from or written to secondary storage.Typically, high-speed caches are implemented in RAM, though they can also be implemented on disk when speed is not a critical requirement. - Page 48 Hot Spare One or more disks in a RAID array may fail at any given time. In fact, all RAID types with the exception of RAID 0 provide methods to reconstruct the array in the event of such an occurrence.A commonly used tactic is to earmark a hard disk that is not being used by any RAID...

- Page 51 C-Glossary RAID 5 A RAID 5 array is similar to a RAID 4 array in that, it utilizes a striped set of three or more disks with parity of the strips (or chunks) comprising a stripe being assigned to the disks in the set in a round robin fashion.The figure below illustrates an example of a RAID 5 array comprised of three disks –...
- Page 52 Read Ahead Motivated by the principle of “spatial locality”, many RAID controllers read blocks of data from secondary storage ahead of time, i.e., before an application actually requests those blocks. The number of data blocks that are read ahead of time is typically governed by some heuristic that observes the pattern of requests.The read-ahead technique is particularly efficient when the spatial...
